Rotor blade for a wind turbine

A rotor blade of an aerodynamic rotor of a wind turbine, the aerodynamic rotor having a rotor axis of rotation and an outer radius, the rotor blade comprising:

• a blade root for fastening to a rotor hub;
• a blade tip facing away from the blade root;
• a blade longitudinal axis extending from the blade root to the blade tip;
• a blade front edge facing toward a front in a direction of movement of the rotor blade;
• a blade rear edge facing toward a rear in the direction of movement of the rotor blade;
• and
• a plurality of profile sections along the blade longitudinal axis,
• wherein each profile section has a profile chord extending from the blade front edge to the blade rear edge, wherein each profile chord has an installation angle as an angle in relation to a rotor plane, and wherein the installation angle from the blade root to the blade tip:
• first decreases in a blade inner region oriented toward the blade root,
• increases again in a blade central region, and
• decreases again in a blade tip region oriented toward the blade tip,
• wherein the installation angle has a local maximum in a region of between 35% and 80% with respect to the outer radius, wherein the outer radius is 100%.

A wind turbine for generating electrical energy, the wind turbine comprising:

• an aerodynamic rotor;
• and
• at least one rotor blade attached to the aerodynamic rotor, wherein the at least one rotor blade includes:
• a blade root for fastening to a rotor hub;
• a blade tip facing away from the blade root;
• a blade longitudinal axis which extends from the blade root to the blade tip;
• a blade front edge facing toward a front in a direction of movement of the rotor blade;
• a blade rear edge facing toward a rear in the direction of movement of the rotor blade;
• and
• a plurality of profile sections along the blade longitudinal axis,
• wherein each profile section has a profile chord extending from the blade front edge to the blade rear edge, wherein each profile chord has an installation angle as an angle in relation to a rotor plane, and wherein the installation angle from the blade root to the blade tip:
• first decreases in a blade inner region oriented toward the blade root,
• increases again in a blade central region from 35% to 60% with respect to an outer radius, wherein the outer radius is 100%, and
• decreases again in a blade tip region oriented toward the blade tip.
